Oh, most of their vertical lines were probably done with the "scratches" parameter of a film damage effect. If you don't have the relevant add-ons, you can make vertical lines with masked planes, Lightswords or lightning. Maybe add a bit of heat Distortion to bend em a little. Same with the horizontal lines. The circle pattern shown at one point could be masked planes or radio waves. They use a photo of the Torchwood sign on a tile wall graded red, and some of the overlays look like scans of pen scribbling on paper inverted, then hue shifted to red. It's all fairly basic stuff, really. Just a lot of quick keyframes.
